thereof into a complete container. The blank comprises a cover forming part hingedly connected to a box forming part. The box forming part comprises hingedly connected front, rear and side wall panels which may be assembled to provide a tubular body and bottom flaps and tabs extending from the lower ends of the front, rear and side wall panels, which may be as sembled to provide the botom wall of the box part. i

The cover part comprises a top wall panel' which is hinged to the rear wall panel of the box part. The top wall panel of the cover part also carries a. front panel or flange section formed to telescope over the outside face of the front wall panel of the assembled box part. A side wall forming panel or section is hinged to each end of the front flange section of the cover part and carries a securing tab which can be secured to the to wall panel of the cover part to retain its assoc ated side wall sectio in a plane extending substantially at right angles to the plane of the front flange section and the plane of the top wall panel. In one form of the invention the securing tabs are secured to the outside face of the top wall panel of the cover part and in another form of the invention the tabs are secured to the inside face of the top wall panel of the cover part.

An abutment flap connected to the front flange section of the cover part, is so shaped and formed as to provide a fixed abutment edge which is adapted to cooperate with the abutment edge of a flap hinged to the front wall panel of the box part to provide means for retaining the cover part in closed telescoped position over the box part and to provide resistance to the opening of the cover part so that the cover part will not normally open until opening force is applied thereto.

The blank is so shaped and formed as to permit automatic assembly of the front, rear and side wall panels of the box part in collapsed tubular form. The partially assembled container may thus be economically shipped and stored with the The blank is so cut and scored as to permit high speed automatic assembly tubular portion of the box part in collapsed form and with the'unassembled cover part extending therefrom. The cover part as well as the bottom wall of the box part may be assembled by I the merchandise manufacturer as the container is needed.

This improved container may be made in any length, width or depth desired, and is adapted for the packaging of various articles of merchandise which have heretofore been customarily packed in metal or other rigid hinged cover containers. Since the containers may be shipped to the merchandise manufacturer as partially assembled collapsed shells, substantial economies in shipping costs and storage space are realized. The merchandise manufacturer can proceed with the final assembly of the box part and the cover part and thereafter load the box part with merchandise by operations which can be performed automatically at high production speeds.

An object of this invention is to provide an improved hinged cover container which may be formed from a single blank of paperboard material and which can be assembled automatically at high production speeds.

Another object of this invention is to provide an improved hinged cove container formed from paperboard material, which can be used for the packaging of various articles of merchandise heretofore normally packaged in metal or other rigid hinged cover containers.

A further object of this invention'is to provide an improved blank of paperboard material adapted for assembly into a hinged cover container byautomatic [machine operations.

A still further object of thi invention is to provide an improved hinged cover container formed of paperboard material, which is attractive and neat in appearance, strong and sturdy in construction and serviceable in use, and which can be manufactured at a fraction of the cost of other hinged cover containers of comparable size and attributes.

Another object of this invention is to provide a container formed from paperboard material having a box part and a cover part hinged thereto and adapted to telescope over the open end of the box part, which is provided with means associated with the box part and cover part adapted to retain the cover part in closed position so as to prevent any undesired opening thereof and which may be nevertheless easily and quickly opened and closed, and which is so constructed that the cover part may be swung completely away from the open end of the box part so as not to interfere with the insertion or removal of the contents into or from the box part.

Other objects of this invention will become apparent as the disclosure proceeds.

The individual box forming blanks as shown in Fig. 1 may be cut and scored from large sheets or rolls of paperboard material possessing the required strength and texture, which operation can be advantageously performed on an automatic cutting and scoring machine at a high production rate. The paperboard sheets or rolls need be finished and imprinted on one side thereof only which can be performed prior to cutting and scoring. The blanks emerging from the cutting and scoring machine are ready for assembly into collapsedassembled shells in the form shown in Fig. 4 on an automatic strip gluing and folding machine, at a high production rate and substantially without hand operation.

Fig. 1 illustrates the inside face view of the prepared blank which comprises essentially a box forming part a and a cover forming part b hingedly connected together along score line 16. The

box forming part comprises a front wall panel I;

a rear wall panel 2, and side wall panels 3 and 4. Front wall panel I is connected by score line 6 along one side edge thereof to the side wall panel 3, the opposite side edge of side wall panel 3 is connected by score line 6' to the rear wall panel 2. and the opposite side edge of rear wall panel 2 is connected to the side wall panel 4 by score line 6". The front wall panel I is provided with a securing flap 5 defined by score line 6", the securing flap 5 being adapted to be ad-' hesively secured to the opposite side wall panel 4. The score lines 6, B, 6" and 6" may be arranged in substantially parallel relationship and extend longitudinally of the blank.

The bottom of the box part is formed by a bottom flap 1 hinged to the lower end of the front wall panel I along transversely extending score line B, and a bottom flap 9 connected to the lower end of the rear wall panel 2 by transversely ex-;

tending score line 8. A bottom tab I0 is connected to the lower end of each of the side wall panels 3 and 4 by a transversely extending score line 8". Score lines 8, 8' and 8" are slightly offset with respect to one another to permit proper folding assembly of the tabs l0 and bottom flaps 1 and 9, as is well known in the art.

The upper end of front wall panel i is provided with a resilient abutment flap H connected thereto along a transversely extending score line I2, which score line may be provided with spaced cuts or perforations l2 to facilitate bending of the abutment flap II. 'The ends of the hinged abutment flap H may be tapered as at l3. The free edge M of the hinged abutment flap ll provides an abutment edge which cooperates with an abutment edge 2i of the fixed abutment flap l9 associated with the cover part b. in the manner more particularly described hereinafter.

The cover forming part -b of the blank comprises more particularly a top wall panel l5 connected by a transversely extending score line 16 to the upper end of the rear wall panel 2 of the box part. A front panel or flange section I! is connected by transversely extending score line l8 to the top wall panel I while the abutment fiap I 9 is connected by transversely extending score line to the front flange section I'I. It will be noted that the score lines I6, I8 and 20 are substantially parallel to one another and extend across the full width of the cover part. It will also be noted that the distance between the transverse score lines I 6 and I8 is slightly and B" which define the side edges of the rear.

wall panel 2, so as to permit the side wall forming sections 22 of the cover part to snugly telescope over the outside face of the side wall panels 3 and 4 of the box part when the container is .fully assembled. The outer ends 26 of the side wall forming sections 22 may be given-an arcuate configuration to enhance the appearance of the cover part.

A securing tab is hingedly connected to each of the side wall sections 22 of the cover part. along the score line 21 which is substantiallya continuation of the score line I8. Each tab 25 is separated from the adjacent end of the top wall panel l5 of the cover part by a out line 29 which extends longitudinally of the blank i and substantially in alignment with the score line 23. Each tab 25 is also separated from the upper end of the side wall panel of the box part by a cut 30. When the box is assembled the tabs 25 are secured to the top Wall panel I5 of the cover part to maintain the cover part in rigid assembly. The tabs 25 may be cut to any desired shape, but-when formed as shown in Fig. 1, stripping out of small Waste portions of the paperboard is wholly eliminated.

It will be noted that the upper ends of the side wall panels 3 and 4 present along the cut 30 a beveled edge 3| and that the rear wall panel 2 is slightly higher than the front wall panel I, with the transversely extending score line I2 out of alignment with and slightly below the score line IS. The hinged abutment flap II and the fixed abutment flap I 9 are substantially the same length as measured longitudinally of the blank and their combined length is slightly less than the length of the front flange I! of the cover part. When the abutment flaps II and I9 are thus proportioned, positiveinterengagement between the respective abutment edges I4 and 2| thereof is assured when the'container is assembled.

The prepared blank as shown in Fig. l is fed into an automatic gluing and folding machine, which may be of the right angled type, with the blank as shown in Fig. 1 being advanced on a continuous conveyor in the direction of the arrow 35 as shown in Fig. 1. During this advance a strip of adhesive 9 is applied to the upwardly facing inside face of the abutment flap I9 and during further progress of the blank the glued flap I9 is folded over into adhesive contact with the inside face of the front flange ll of the cover part.

The blank then changes its course of travel so as to move in the direction of the arrow 38 as shown in Figs. 2, 3 and 4. During this second stage of travel a strip of adhesive 9 is applied to the outside face of the securing flap 5. Following this gluing operation the front wall panel I is folded about score line 6 so as to overlie the inside face of' the side wall panel 3 and the rear wall panel 2, as illustrated in Fig. 3. During further travel of the blank, side wall panel 4 is folded about the score line 6" so that its free edge overlies the glued securing flap 5. Suitable pressure rollers or similar devices then come into play to press the side wall panel 4 into firm adhesive engagement with the securing flap 5, producing the collapsed assembled shell as shown in Fig. 4.

The collapsed assembled shell shown in Fig. 4 may be assembled on an automatic strip gluing and folding machine at speeds as high as 20,000 per hour or higher. The collapsed assembled shells emerging from this machine may be stacked in boxes or packages in a minimum of space and shipped to the merchandise manufacturer in this condition at a great saving in transportation cost as compared with fully erected containers. The merchandise manufacturer can store the collapsed assembled shells until such time as merchandise is to be packed therein. The merchandise manufacturer may be equipped with automatic high speed assembly machines for completing the assembly of the boxes and packaging the same with merchandise.

When merchandise is to be packed in the collapsed assembled shell as shown in Fig. 4, the body of the box part a is erected into the tubular form shown in Fig. 5. If desired, the merchandise can then be inserted into the expanded box part or the merchandise can be inserted, if desired, at a later stage in the assembly operations. The blank is so constructed as to permit simultaneous assembly of the bottom end of the box part and the cover part by a series of assembly operations illustrated in Figs. 6 to 11 inclusive.

The assembly operation may be performed while the rear wall panel 2 of the container rests in a horizontal position on a continuous moving conveyor and while the shell advances in the direction of the arrow 31', shown in Figs. 6 to 11 inclusive.

During the travel of the shell in the direction of the arrow 3'! as shown in Fig. 6, the leading bottom wall tab I0 is first folded inwardly, followed by the inward folding of the trailing bottom tab ID as shown in Fig. '7, so that both tabs substantially align with the score line 8. During further continued travel of the expanded shell in the direction of the arrows shown in Figs. 6, 7 and 8 the bottom wall flap 9 is folded upwardly to overlie thetab I0 and substantially simultaneously the top wall panel l5 of'the cover part is erected into the vertical position shown in Fig. 8. When the top wall panel I5 i so positioned the front flange forming section I! will also extend upwardly and the hinged abutment flap u will rest against the inside face of the flange section I'I. As shown in Fig. 8, the abutment edge I 4 of hinged abutment flap II and the abutment edge 2| of fixed flap I9 will be slightly spaced apart with the flap I I and I9 substantially in alignment.

At the next operation and during further progress of the partially assembled blank in the direction of the arrow 31 as shown in Fig. 9', the front flange section I1 of the cover part is folded downwardly so as to overlie the outside face of the front wall panel I of the box part. While the front flange I1 is held in this position, the partially assembled box advances over glue rollers G, shown in Fig. 9, which operate to apply a strip of adhesive to the under surface of the bottom wall flap I of the box part and to the under surface of each securing tab 25 of the'cover part which project laterally beyond the top wall panel I5 of the cover part when th front flange section I! is in downfolded position.

In the next operation and during travel-of the partially assembled box in the direction of the arrow 3! as shown in Fig. 10, the bottom wall flap I is folded into adhesive engagement with the outside face of the upturned bottom wall flap 9 and substantially simultaneousl the side wall sections 22 of the cover part are folded downwardly so as to overlie the adjacent side wall panels of the box part.

As the final assembly operation and while the box assembled as shown in Fig. 10 moves in the direction of the arrow 31, the securing tab 25 at the advancing edge of'the' shell is folded rearwardly into adhesive contact with the outside face of the top wall panel I 5, and substantially simultaneously the trailin securing tab 25 is folded forwardly into adhesive contact with the outside face of the top wall panel I5. As thus assembled the container appears as shown in Figs. 11 and 12 with the cover part in closed position over the box part.

There is shown and illustrated in Fig. 16 an inside face view of a prepared blank which is similar to the blank shown in Fig. 1 and presents substantially the same elements, except that certain elements have been rearranged. The cntainer formed from the blank shown in Fig. 16, however, has the same exterior appearance as the containers shown in Figs. to 15 inclusive, except that the securing flap 5 of the blank shown in Fig. 16 is secured to the free edge of the rear wall panel 2, whereas the securing flap 5 shown in F g. 1 is secured to the free edge of the side wall panel 4. In the blank shown in Fig. 16 the securing flap 5 is connected to the side wall panel 5 along the longitudinally extending score line 6".

panel I5 pressed into adhesive engagement with the flap extension 5', and with the free side edge of the front wall section I! pressed into adhesive engagement with the flap extension 5". thus assembled the blank shown in Fig. 16 will have substantially the same exterior'appearance as the assembled collapsed blank shown in Fig. 5 and the erection and assembly of the blank shown in Fig. 16 may be similar to the assembly steps illustrated in Figs. 5 to 11 inclusive. The finished box would appear substantially as illustrated in Figs. 12 and 13.

The container illustrated in Fig. v1'7 may be formed from the blank shown in Fig. 1 or the blank shown in Fig. 16. This container is identical with the container illustrated in Fig. 13 except that the securing tabs associated with the cover part .of the container shown in Fig. 17 are secured to the inside face of top wall panel I5 rather than to the outside face thereof as illustrated in Fig. 12. The particular succession of steps for assembling the container shown in Securing flap 5 is also provided with an extension 5' connected to the upper end thereof by a transverse score line I6 which aligns with the score line I6 and a further extension 5" connected along a transverse score I8 to the upper end of extension 5. Transverse score line I8 aligns with the transverse score line I8.

Also, one of the side wall sections 22 of the cover part is hinged to extension 5" along longitudinally extending score line 23 which is substantially in al gnment with the score line 6". Securing tab 25 is separated from the securing flap extension 5 by a out line 29 and is hinged to the adjacent side wall section 22 by the transverse score line 21 which is substantially in alignment with the score line 2'! which joins the end of the score line I8.

In assembling the blank shown in Fig. 16, a

- strip of adhesive is applied to the under face of the securing fiap 5 and flap extensions 5' and 5", and the side wall panel 4 is then folded about the score line 6 so as to overlie the inside face of front wall panel I. Rear wall panel 2 is then folded about score line 6 so as to overlie the side wall panel 3 and a portion of the front wall panel I, with the free side edge of the rear wall panel 2 pressed into adhesive engagement with securing flap 5, with the free edge of the top wall Fig. 17 have not been illustrated since they form no part of this invention.

On completion of the container the cover part b is swung open, as shown in Figs. 13 and 17, and the merchandise plug P is inserted into the box part, which operation'can beautomatically performed. .The cover part is then swung into closed position with the abutment edge I4 of the hinged abutment flap II abutting the abutment edge 2| of the fixed abutment element or flap I9. By reason of the beveled upper edges 3I of the side wall panels 3 and 4, the top wall panel I5 may be pressed downward so as to lie at substantially an acute angle to the rear wall panel 2. Since the abutment elements I I and I9 have a combined length which is less than the comparative length of the front flange H of the cover part, the abutment edge 2I of the fixed abutment element-I9 isentirely free to swing under and engage the abutment edge I4 of the hinged abutment flap I I when the top wall panel I5 of the cover part is pressed so as to substantially abut the beveled upper edges 3| of the side wall panels 3 and 4. Due to the inherent resiliency of the paperboard material, top wall panelv I5 will swing upwardly into substantially horizontal position and substantially at right angles to the rear wall panel 2 when pressure on the top wall panel I5 is released. When this occurs, abutment edge 2| of the abutment element or flap I9 will engage and abut the abutment edge I I of the hinged abutment flap I I.

When access to the contents is desired, upward pressure is exerted on the lower free edge of the front flange II of the cover part. Stresses are thus imposed upon the front wall panel I and the rear wall panel 2 of the box part, causing them to bow inwardly as illustrated in Fig. 15. The stresses thus engendered resist opening of the cover part and maintain the cover part in positive closed position until sufficient upward force is exerted on the front flange I1 of the cover part to overcome this resistance. However, a relatively slight downward forceonly need be exerted on the top wall panel I5 of the cover part to effect closing of the cover part. Resistance to opening of the cover part continues until the hinged abutment flap II extends at substantially an obtuse angle to the front wall panel I. The hinged abutment flap Hand the fixed abutment element or flap I9 are so'shaped and proportioned as to ofier the desired resistance to the normal opening of the cover part, so that the cover When part is retained in closed position and will not open during normal handling of. the container. The cover part can only be opened by applying force to the front flange section I1 of the cover part sufficient to overcome the resistance offered by the hinged abutment flap H and the fixed abutment element or flap l9.

The blanks shown in Figs. 1 and 16 can be cut and formed at high speed on an automatic cutting and scoring machine. The paperboard sheets or rolls need be finshed on one side only and may be imprinted before the blanks are cut. The individual blanks can be glued and assem bled in collapsed form, as shown in Fig. 4, in whichcondition they can be economically shipped and stored. The blank is so formed and proportioned as 'to permit high speed automatic assembly and packaging of the containers by -a few high speed assembly operations.
